Hello,
CMPS and SCAS instructions accept repeat prefixes F3 and F2. So in
order to emulate those prefixed instructions we need to be able to know

this distinction. This patch introduces this distinction.

Can you just rename this to REP and REPNE?
Yes I can. I send the new patch.
Does this fix the problems you saw with openbsd?
No not yet. It will help to make the difference between REPE prefix and
REPNE prefix because
